About cancer

Cancer is a disease that affect the cell. We know that cell is the body's basic unit. Cancer occurs when cells become abnormal and divide without control. As a basic unit of body, cell formalize tissue that formalize organ and the body.Like all other organs of the body, the colon and rectum are made up of many types of cells. Normally, cells divide to produce more cells only when the body needs them. This orderly process helps keep us healthy.
But this can happen: cells keep dividing when new cells are not needed; then a mass of tissue forms. This mass of extra tissue called a growth or tumor. It can be benign or malignant.
Benign tumors are not cancer. It is a mild one. They can usually be removed and, in most cases, they do not come back. Most important, cells from benign tumors do not spread to other parts of the body. Benign tumors are rarely a threat to life.


Malignant tumors are what we call as cancer. Cancer cells can invade and damage tissues and organs near the tumor. Also, cance cells can break away from a malignant tumor and enter the bloodstream or lymphatic system. This is how cancer spreads from the original (primary) tumor to form new tumors in other parts of the body. The spread of cancer is called metastasis. Cancer metastasis can reach almost all part of body. How far and how dngerous cancer metastasis it show by cancer stadium or cancer stage.
When cancer spreads to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary tumor. For example, if colon cancer spreads to the liver, the cancer cells in the liver are colon cancer els. The disease is metastatic colon cancer.
